It is commonly convenient to make use of individual settings for build configurations. In the C/C++ build settings one can then change individual configurations, or all at the same time. When changing all at the same time (configuration: [All configurations]), the command line pattern for create extended listing and print size are always both written. That is, modifying the line for print size will also copy that same line to the create extended listing line pattern, creating havoc there.
This happens at least for a static library project, but I suspect it always happens, and I also suspect this may not be the only place where it happens. I've had my input messed up frequently with seemingly unrelated edits.
